HP Envy 7640: Printer will not print on Server 2008 but will on Windows 10

Sun, 30 Jul 2023 01:59:18 -0700

I know Windows Server 2008 is a little old, but it works for what I am using it for! I am trying to install this printer on the server and it will install the drivers and software just fine, but when I click print it says it is printing but will not do anything, there is not any response on the printer.

I did the same thing on a Windows 10 computer and it all worked first shot, the only difference was I was using wireless rather than USB. I have tried using USB and Ethernet on the Server computer and both end with the same results.

I have contacted HP but they will not help due to the Operating System. I have tried uninstalling and reinstalling, getting the IP and manually adding it to the printer in the Printers section, and also uninstalled and reinstalled the driver, updated the driver with all the same results.

Any help would be much appreciated!

While my printer is printing we hear a very load noise almost as if it is struggling or grinding. Also, when a page is printed, it's not clear seems as if it doesn't print properly and the ink is almost full so should print clearly. Thank you for any help.

HP Envy 7640: black copy from glass . saturated with ink

Fri, 31 Jan 2020 02:25:20 -0700

copier works great from computer. copies from glass or feeder comes out completely covered in black, grey ink. Same results if nothing is on the glass. scanning light works.

Maybe a new one is in the works?

HP Envy 7640: Printer will not print

Fri, 20 Sep 2019 05:23:19 -0700

Printer makes an electrical noise that almost sounds like burning, but has no burning smell. The printer will not print during this time of the noise. After several minutes, the noise stops and the printing is completed.

HP Envy 7640: Is it possible to improve, lubricate or replace the scaner roller

Tue, 02 Apr 2019 11:15:01 -0700

I’ve had the HP Envy 7640 all-in-one printer for a little over a year. I am wondering if there’s any way to lubricate, improve, repair or replace the roller located in the document feeder? I guess I’m asking if this is possible.. Much like you lubricate the roller-shredder on a paper shredder - using either the pre-lubricated paper sheets or the oil itself.. Thank you.

hp envy 7640: Why can't I print on .2mm thick paper?

Sun, 16 Apr 2017 21:45:21 -0700

I am tying to use my HP Envy 7640 to print on Cricut's Printable Sticker paper. It keeps making the noise of grabbing the paper and printing but the paper either gets jammed, comes out blank, or prints only a bottom portion of the image. The paper is said to be .2mm thick.

HP Envy 7640: What is blocking the Photo tray when I want to print using normal tray

Thu, 13 Nov 2025 11:06:48 -0700

Photo tray is in proper place but once I hit print using normal tray, it clicks and stops, then printer stops and produces error message about Photo Tray Problem. It is riding freely and I definitely in place per HP fixit page. I'm not trying to print photos, just normal print/copy from regular tray. "The photo tray is blocked. Please adjust the tray and try again." Purchased in 2018, HP ENVY 7643.
